UPJ1V271MPD

The UPJ1V271MPD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon's UPJ series. It is a radial-lead can designed for general-purpose power applications, with features that target low impedance and reliable long-term operation under thermal stress.

Key value comes from its 270 µF capacitance at 35 V, low loss (tanδ 0.12 at 20°C, 120 Hz), and a 5000-hour load life at 105°C, making it suitable for power filtering and decoupling in switching power supply designs and other general-purpose electronics.

Key Features

• Capacitance & Rated Voltage — 270 µF nominal capacitance with a rated voltage of 35 V and tolerance of ±20%.
• Low Loss / Low Impedance — tanδ = 0.12 (20°C, 120 Hz) supporting low impedance behavior beneficial for power supply filtering.
• Ripple Current Capability — Low-frequency ripple current 418.95 mA at 120 Hz and high-frequency ripple current 735 mA at 200 kHz, useful for handling dynamic load currents.
• Leakage Current — Specified leakage current of 283.5 µA (consistent with standard measurement conditions at 20°C after 1 minute).
• High Temperature Endurance — Rated endurance of 5000 hours at 105°C for the φ10 case size, supporting sustained high-temperature operation.
• Operating Temperature Range — −55°C to +105°C for broad environmental tolerance.
• Compact Radial Package — φ10 × 20 mm can with 5 mm lead spacing (±0.5 mm), radial lead mounting for through-hole designs.
• Compliance & Packaging — RoHS compliant; available in Bulk (No Terminal Forming) or Bag packing; part is in mass production.

Typical Applications

• Switching Power Supplies — Low impedance characteristics and specified ripple current make this capacitor suitable for input/output filtering and smoothing in switching regulators.
• General-Purpose Power Filtering — Bulk decoupling and smoothing in a wide range of electronic equipment that requires stable capacitance across −55°C to +105°C.
• Compact Through-Hole Designs — Radial lead can (φ10×20 mm, 5 mm lead spacing) for designers needing a small, serviceable electrolytic capacitor in through-hole assemblies.

Unique Advantages

• Long High-Temperature Life — 5000-hour endurance at 105°C for the φ10 case supports designs that must operate under elevated temperatures without frequent part replacement.
• Low Loss for Stable Performance — tanδ 0.12 at 20°C, 120 Hz contributes to lower heat generation and predictable behavior in AC ripple environments.
• Measured Ripple Ratings — Specified LF and HF ripple current values let engineers size capacitors confidently for both mains-frequency and high-frequency switching environments.
• Compact, Through-Hole Form Factor — Small φ10×20 mm can and 5 mm lead spacing save board space while maintaining the convenience of radial-lead mounting.
• RoHS Compliance and Production Availability — Environmentally compliant and available in mass production with standard bulk/bag packaging options.
